-fixed installing gamecube disc 2 with wiiflow installer
-fixed exit to neek2o for people who got their nand in a folder
-some general cleanup and speedup
-if a IOS is found which got the AHBPROT patched out, wiiflow will
run on it (for example if you boot wiiflow via HBC, it will boot
with IOS58 instead of 249)
-on game boot or on entering emu nand, wiiflow automatically reloads
IOS if necessary
-added check to only reload IOS if its really a different one
-removed SD card gecko log buffer allocation, using some
buffer in dol directly (should allow longer logging, untested)
-set wiiflow optimize level back to -O2
